MORITZ LEINER, OF NEXV YORK, N. Y.

POLISHING-BRUSH;

SPECIFICATION forming part of Letters Patent No. 616,677, dated December2'7,

Application filed April 20, 1898- Seria1No.678,248. (No model.)

To aZZ whom it may concern:

Be it known that I, MORITZ LEINER, a citizen of the United States,residing at New York, in the borough of Bronx, State of New ork, haveinvented certain new and useful Improvements in Polishing-Brushes, ofwhich the following is a specification.

This invention relates to brushes; and the object of the invention is toprovide a simple and durable brush which is in the end less costly thanthose at present in use.

This invention consist of a suitable cylindrical body provided at one orboth ends with an annular flange oifset therefrom, substantiallyC-shaped brush-sections composed of twisted-wire cores having radiatingbristles, one end of each of said cores being bent or engaged over saidflange, and means for holding said ends in position, as will behereinafter described and then particularly claimed.

In the accompanying drawings, Figure 1 is a perspective view of one formof brush embodying my invention. Fig. 2 is a diametrical section of thesame, showing one of the brush-sections about to be applied thereto.Fig. 3 is a view, on a reduced scale, looking at the brush from theopposite side of Fig. 1. Figs. 4 and 5 are small detail views of severalmodifications; and Fig. 6 is another modification, showing a flange andretaining-ring at each end of the brush-body.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, Figs. 1 to 3, inclusive, A indicates thedisk-shaped body of a bu fling-brush, which is preferably composed ofwood or similar material, said disk being encircled by a circumferentialband B, of sheet metal, said band being offset or extending beyond thebody of the disk at one or both ends, so as to form an annular sideflange 1). Into the central hole of the disk-shaped body A is inserted asuitable spindle G. The body A and the band B may be of different shapesand sizes, according to the form of brush which is desired to beproduced.

The bristle portion of the brush, which is applied to thecircumferential rim B or the periphery or outside of the body A, iscomposed of brush-sections D, which are arranged upon the disk or body Aso as toextend parallel with each other and transversely across thecircumference of said body. Each brushsection D is composed of a centercore d, of twisted wires, between which are held the bristles d, so thata cylindrical brush-section is produced. In order to apply thebrushsection D to the body A, the side or face of the same opposite tothe flange b is preferably provided with a series of perforations a,concentric with the axis of the disk or body, said perforations being ofa'number corresponding with the brush-sections to be applied. As evidentmodifications to meet the requirements and different forms of brushesthe perforations may be displaced by recesses or annular grooves or thebrush-sections may be suitably held in any preferred manner at that sideor end of the disk or body.

To attach the brush-sections to the body or disk, one end of each coreof the brush-sections, as shown plainly in Fig. 2, is inserted in one ofthe perforations or sockets a. The wire core is then bent at an angle tothe inserted end, so as to extend a short distance radially on the disk,the body of the brushsection being then bent and returned in practicallythe same direction as the inserted end, so as to extend parallel withand transversely across the periphery or outside of the body A, theopposite end of the wire core being then reverted or bent inwardly, soas to form a hook (P, which is engaged over the offset flange b at theopposite side of said body a. The cores of the brush-sections D arecomposed of some pliable metal which is not lia ble to break in bending,and when the said sections are arranged in position the bristles incontact with the supporting-surface will be flattened out, while thosenot in contact with the same will extend in a curve or semicircle fromone side of the brush-section to the other, so that when a number ofbrushsections are arranged alongside of each other a nearly cylindricalbrush for buffing and polishing purposes is obtained. The brush-sectionsbeing thus applied one after the other and being pressed so as to form acompact bristle surface, the said brush-sections are ready to be firmlyfastened in position. This is done by inserting within the space formedwithin the offset-flange b a retaining device or ring E, which issomewhat smaller than the flange b, so that an annular groove or re--Nu. 6I6,678.- Patented Dec. 27, I898.
